In this activity, learners examine how brine shrimp populations can survive in some of the harshest environments.

In this activity, learners discover how frogs' bodies change while growing from a tadpole to a frog. Learners create a simple craft that gives a visual display of the metamorphosis process.

In this activity, learners examine body parts (including skin, scales, and skulls) from fish, mammals and reptiles. Questions are provided to help encourage learner investigations.

In this outdoor beach activity, learners use a variety of "beaks" (such as trowels, spoons or sticks) to hunt for organisms that shore birds might eat.

In this activity, learners explore how casts of fossilized bones are created and used to learn about dinosaurs. Learners make observations, draw diagrams and share their findings.

In this activity, learners play bingo to learn about the diversity of birds. This game includes a warm-up lesson and "Full Flight" version.

In this outdoor activity/field trip, learners catch and observe water striders to explore their movement and feeding behaviors.

In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

In this activity, learners experience firsthand how marine animals' adaptive coloration camouflages them from prey.

In this experiment, pairs of learners explore how cold water affects circulation. The mammalian diving reflex (MDR) slows circulation when the body is exposed to cold water.

In this outdoor activity/game, learners use thermometers to simulate how lizards survive in habitats with extreme temperatures.

In this outdoor activity and animal-role-play game, learners discover and uncover the hidden world of "cryptozoa"—organisms such as spiders, salamanders and slugs that live under objects, like rocks a

In this activity, learners learn about the adaptations that flowers have developed which support pollination. Learners also list their personal preferences (i.e.

This activity is intended to familiarize learners with native Houston birds, introduce learners to tools biologists use in the field, and to enhance their observation skills.

In this data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr.

In this outdoor, ocean-side activity, learners investigate the distribution of organisms in the upper region of the intertidal zone.

In this activity and/or field trip, learners investigate the water currents that aquatic animals create when they breathe, feed, and propel themselves through water.

In this activity (6th on the page), learners investigate how photoreceptors in the eye (rods and cones) "adapt" to low light conditions.

In this outdoor activity and game, learners explore how animals adapt for survival through coloration, markings and camouflage.

In this engineering design challenge, learners build an octopus-inspired suction pad that can grab an object and hold it tightly in the air.
